A guide for creating images, video, audio, and 3D content with ComfyUI, a visual system for connecting AI-generation steps into workflows. It covers installing and running ComfyUI, managing models and nodes, and executing workflows through its interfaces.

Use it to install and launch ComfyUI, check whether local hardware is suitable, run local or cloud workflows, inject parameters, inspect workflow inputs, and troubleshoot common template or cloud-format issues.

It brings setup, workflow structure, parameters, and hardware or cloud considerations into one place. This reduces confusion when adapting official workflow templates or deciding how to run them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00046	$0.06342
Opus 5	$0.00023	$0.03171
Sonnet 5	$0.00009	$0.01268
Haiku 4.5	$0.00005	$0.00634

Security

Grade B, and why

comfyui scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 17 executable files (scripts/_common.py, scripts/auto_fix_deps.py, scripts/check_deps.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -X POST http://127.0.0.1:8188/queue -d '{"clear": true}' # cancel pending

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

curl -s http://127.0.0.1:8188/queue | python3 -m json.tool

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 613 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ComfyUI

Generate images, video, audio, and 3D content through ComfyUI using the official comfy-cli for setup/lifecycle and direct REST/WebSocket API for workflow execution.

What's in this skill

Reference docs (references/):

official-cli.md — every comfy ... command, with flags
rest-api.md — REST + WebSocket endpoints (local + cloud), payload schemas
workflow-format.md — API-format JSON, common node types, param mapping
template-integrity.md — converting comfyui-workflow-templates from editor format to API format: Reroute bypass, dotted dynamic-input keys (values.a, resize_type.width), Cloud quirks (302 redirect, 1 concurrent free-tier job, 1080p VRAM ceiling), Discord-compatible ffmpeg stitch. Authored by @purzbeats. Load this whenever you're starting from an official template.

Scripts (scripts/):

Script	Purpose
`_common.py`	Shared HTTP, cloud routing, node catalogs (don't run directly)
`hardware_check.py`	Probe GPU/VRAM/disk → recommend local vs Comfy Cloud
`comfyui_setup.sh`	Hardware check + comfy-cli + ComfyUI install + launch + verify
`extract_schema.py`	Read a workflow → list controllable params + model deps
`check_deps.py`	Check workflow against running server → list missing nodes/models
`auto_fix_deps.py`	Run check_deps then `comfy node install` / `comfy model download`
`run_workflow.py`	Inject params, submit, monitor, download outputs (HTTP or WS)
`run_batch.py`	Submit a workflow N times with sweeps, parallel up to your tier
`ws_monitor.py`	Real-time WebSocket viewer for executing jobs (live progress)
`health_check.py`	Verification checklist runner — comfy-cli + server + models + smoke test
`fetch_logs.py`	Pull traceback / status messages for a given prompt_id

Example workflows (workflows/): SD 1.5, SDXL, Flux Dev, SDXL img2img, SDXL inpaint, ESRGAN upscale, AnimateDiff video, Wan T2V. See workflows/README.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
